Source: kam193 (88b61508de8bb1a4224db6f1b2c7f8784f678f59e6ecacfac77c0a7d3f0409df)
Installing the package or importing the module exfiltrates basic information about the host, and the package has no other purpose.
Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.
Campaign: GENERIC-standard-pypi-install-pentest
Reasons (based on the campaign):
-
The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.
-
The package overrides the install command in setup.py to execute malicious code during installation.
